I finally have my Ateo Pixel64 running reliably (90% of the time) with P96!
One thing has me scratching my head, though.
I know that I used to be able to to run OS-friendly AGA games and apps launched from Workbench. But now I think that was when I booted my Amiga in such a way as to boot into a native screen mode AGA Workbench by essentially preventing the gfx card from initializing, by not allowing "C:startateobus to launch. For various reasons, it now seems that this approach no longer works, and that other than commenting out the relevant line in startups-sequence, I cannot boot without the gfx card initializing.
And if I try to run, for example, a native chipset whdload game, or a HD-installable game like Monkey Island 2 from a P96 WB screen, it'll make the WB screen go black and the Amiga locks up completely.
Am I doing something wrong, or have I simply forgotten with time how RTG is supposed to work?
